Detailed Description

The invention will be described in further detail with reference to the drawings and specific examples.

Example 1

As shown in fig. 1: a building component reinforcing structure comprises a column body 1, wherein at least one side wall of the column body 1 is provided with a concave part 2.

The scheme has the following advantages: through set up the concave part at the lateral wall, can play the stiffening, can need not to set up the gusset like this on the cylinder, perhaps need not to set up the gusset of more quantity on the cylinder, can adopt a small amount of gusset can, the concave part can be directly extruded on the production line moreover, need not like the gusset at the installation of mill, labour saving and time saving.

The cylinder 1 of this embodiment is the channel-section steel structure, and its one side is equipped with uncovered 11, and other faces (including top surface, bottom surface and three lateral wall) are sealed, and has all seted up concave part 2 on other lateral walls except uncovered, and concave part 2 is seted up along the length direction of cylinder 1, link up from the top of cylinder 1 to the bottom promptly and set up. The cross-sectional shape of the recess 2 may be an arc, square, V-shape or trapezoid, and the present embodiment is preferably an arc.

In the present embodiment, the opening direction of the recess 2 is toward the outside of the column, that is: the concave part is convex towards the direction of the inner cavity of the column body, so that the convex surface faces the inner cavity of the column body, and the opening of the concave part faces the outside of the column body. Thus, the outer surface of the cylinder can be kept flat. Because when the column body is used for buildings and other buildings, an insulating layer and/or a fireproof layer are required to be arranged on the outer surface of the column body, if the convex surface of the concave part is arranged outwards, the insulating layer or the fireproof layer is also required to be provided with a matched convex surface, and the processing difficulty is increased. And the structure of this embodiment can make heat preservation or flame retardant coating set up more simply, on the basis that improves cylinder intensity, has also guaranteed the convenience of installation. The heat-insulating layer or the fireproof layer can be fixedly connected through a column body in a gluing mode or fixed in a gluing and screwing combined mode.

In this embodiment, the vertical distance between the salient point of the concave portion 2 and the corresponding surface of the column 1 is preferably not more than 5mm, that is, the opening depth of the concave portion 2 does not need to be too large, and if the opening depth is too large, deformation is easy to occur, only a concave pit is needed.

In this embodiment, the wall thickness of the cylindrical body 1 is not more than 8 mm. If the wall thickness of the cylinder is larger than 8mm, the concave part does not need to be arranged, and the cylinder has certain strength due to the large thickness. And when the wall thickness of cylinder is less than or equal to 8mm, the intensity of cylinder can weaken, therefore, this embodiment sets up the concave part, can improve the intensity of cylinder, even the cylinder receives expend with heat and contract with cold, also can adjust through the concave part, makes the cylinder have certain elasticity.

In this embodiment, the open side of the column is not provided with ribs.

In this embodiment, when the column body 1 is connected to other building components, a threaded hole is formed in at least one side wall of the column body 1, and the threaded hole is formed at a position other than the recessed portion, so as to ensure flatness. The top surface of the column body 1 is provided with a flange plate 3 for facilitating the connection between the upper and lower column bodies, as shown in fig. 2.

Example 2

As shown in fig. 3: the difference from embodiment 1 is that, in addition to the recess 2, a small number of rib plates 4 are connected to the open end 11 side of the column, but the number is much smaller than that without the recess. Compared with the prior art, the column body of the embodiment has higher strength under the condition that the number of the rib plates is the same; under the condition of the same strength, the number of the rib plates is less.

Example 3

The difference from example 1 is that the building element is a beam, such as a long beam, connected between columns. The long beam is also of a channel steel structure, and concave parts are arranged on other surfaces except the opening.

In addition, because the long beam is large in size, the cavity of the long beam is provided with a certain accommodating space, and a certain number of loose parts can be accommodated in the cavity of the long beam. When the column body and the beam body of the embodiment are assembled to form the container or the die carrier, the bulk parts can be placed in the cavity of the long beam for transportation in the transportation process, and after the bulk parts are constructed on site, the bulk parts are taken out for assembly, so that the space utilization rate is greatly improved. The loose parts can be small-sized support rods, movable beams and the like.

To sum up, the utility model can greatly improve the strength of the building component without rib plates or more rib plates, thereby greatly simplifying the installation steps and the structure and saving time and labor; on the other hand, on the basis of improving the strength of the building member, the smoothness of the outer surface of the building member can be ensured so as to facilitate the installation of an insulating layer or a fireproof layer and the like; furthermore, the utility model discloses mainly to the less building element of thickness, to this type of building element, can improve intensity greatly.
